Roger Federer claimed the 84th title of his legendary career, kept his nose in front in his personal rivalry with Novak Djokovic, and equaled his best achievement at any tournament by winning the Dubai Open for the seventh time on Saturday.

Top-seeded Rafael Nadal overcame the stiffest test so far in his first clay-court tournament of the season, defeating No. 6 Pablo Cuevas of Uruguay 4-6, 7-5, 6-0 to reach the semifinals of the Rio Open.

Yoshihito Nishioka, a 19-year-old from Japan, became the first teenage qualifier to reach the quarterfinals of the Delray Beach Open since his countryman, Kei Nishikori, won the title as an 18-year-old in 2008.
